The value of x is [tex]x=-1[/tex]

Explanation:

The given expression is [tex]18+8 x=-x-3(1+4 x)[/tex]

We need to find the value of x.

To determine the value of x, let us solve the expression for x.

Multiplying the term 3 within the bracket, we have,

[tex]18+8 x=-x-3-12 x[/tex]

Simplifying, we get,

[tex]18+8 x=-13x-3[/tex]

Adding both sides of the expression by 13x, we have,

[tex]18+21x=-3[/tex]

Adding both sides of the expression by 18, we get,

[tex]21x=-21[/tex]

Dividing both sides of the equation by 21, we get,

[tex]x=-1[/tex]

Thus, the value of x is [tex]x=-1[/tex]
